v My invention relates to closures forconr .tZUDGlS such as tumblers,]ars or 'others1m1-1 l'ar containers, embodyin'gfcertainfeatures or andbeing in the. natureioi". animprovement.

over the structuresshown;and described in my co-pendingapplication,Se1-ial Number 685,530. i More specifically, my inventionrelatesto bottle closures of a:type'consistingfof. a top portion anddepending. flange porti'onythe latter being formed with .aperipheral-bead.

near its lower extremity and-having a cutaway portlon 1n. the said beadfor the intr.o'-.

duction of a suitable prying implement. A

score line has generally been disposed so as to cross this-cut-awayportion or slot.

It has been found in practice that when a cap has been-scored so as. tohave the score line crossing or bordering thecut-away portion or slot intheflange', much d-ifli'culty has been experienced 1n the sealingoperation from tears occurring at: the cut-away' por-v tion andextending along the: scoring. line; Such tears "arising during thesealing opera:-

tion, are very objectionable. Thesegn'egatede portions are weakened andelongaterhby virtue of the" aforesaid tears and are unable: to beproperly erimpe-d on the header the:

bottle neck. Furthermore, the cap is obviously lacking in strength fromsuch 'a construction.

An object of my invention is to produce practical and simple means forobviating the above disadvantages in a simple and prac tical manner.

A further object of my invention is to pro-' vide means whereby a cap orclosure is kept" from tearing during the sealing operatlon bottle and myimproved closure device, and] showing the use of asuitable implement toseparate the removable sealing strip. 7

Figure 4 is a fragmentary elevation, partly in section, of my improveddevice, adapted to another form of bottle.

4 Referring nowlto the-drawings. for a: de-

scription in detail ofmy invention illustrated therein, th ere will heseenacl'osure or cap 5- comprising a top portion 6,and a depending:flange or skirt 7. There is formed: lITl'ihG; 'depending'flangeT, alittle above the margin. of said flange, a rib 8rextending circum--ferentially of the flange; There is further tormed'in the dependingflange 7, a slot'lO extending: upward front the lower edge: of theflange to-or through the rib1-8, permittingi the insertionof: asuitableprying; implement 12 under the aforesaid rib 8. The lower margin ofthedependi'ng flange orskirt 7 is vterm-ed to extenddownwardly alittlepast the rim '13: otthe bottle overlwh-iclrit is to fit and provide a:suflicientl edge. to: allow crimping thecap to the bottle: finish. Aboveferentialscore line 11 f0r separating-thesaid the said rib 8'andtthesaid slot;10'-,acircumflange into two part'szisformed in the aforetsaidflange 7. gasketl t made of cork or:

other suitable: materi a1, is disposed within the? cover 5; "Figure l,it will be noted, discloses a similar construction, as: above described,but applies the-principlesot my invention: to a bottl'eaotnarrower'neck. In the use of my, invention-,.: thei closure 5, with the gasket 14inserted therein, :is pl'aced upon-the bottle it is to close, and thelower margin 9is bent under the rim 13 of the bottle neck, therebycrimping the closure of said bottle. I contemplate, in my invention, todispose the score line 11 across the flange 7 a little above the rib 8and the slot- 10 therein. With this arrangement, accidental tearing ofthe flange atthe slot during the above sealing operation, is avoided.

For opening the -'bottle,a suitableimple ment 12' is inserted throughthe slot 10 under the rib 8, and pressed upwardly, causing a tear of therib portion of the skirt along the score linell. The amount 15 so torn,affords a gripping 'means for further tearing by hand and therebycompletely removing the removable strip or sealing band below the scoreline, leaving acomplernentary cover 16 for temporary use during thedispensation.

of the contents of the container.

. Modifications of the above, may be made within the spirit and scope ofmy invention;

VVha-t I claim is:

1. A receptacle closure having a marginal portion adapted to overlie anexterior por tion of a receptacle, said marginal portion ing alsoprovided with a peripheral score line spaced apart'from said peripheralbead and cut-away portion.

3. A bottle closure comprising a top and a skirt portion, said skirtportion having its lower marginal portion provided with sealing andopening means, including a marginal extremity for crimping the saidclosure to a bottle, and a peripheral score line spaced above aperipheral bead formed in the said skirt, said bead being provided withan aperture therein for the insertion of an opening implement, saidaperture being spaced from the score line.

4'. A receptacle closure comprising a top cover portion and a marginalflange, said flange formed with a score line extending lengthwisethereof and also formed with a slot extending upwardly from the loweredge'of the flange and terminating at a point spaced below the scoreline.

5. A receptacle closure comprising a top:

coverportion and a marginal flange, said flange formed with a score lineextending lengthwlse thereof and also formed with a slot extendingupwardly from the lower edge of the flange and terminating at a pointspaced below the score line, said flange also formed with acircumferential bead beneath the scorevline and into which said slotextends.

6.- A sheet metal closure comprising a top portion and an integraldepending flange, said flange being formed with a bead extendingcircumferentially thereof and also formed with a circumferential scoreline above the bead, said flange being formed with a slot extendingupward from the lower edge of the flange into the bead and having itsupper end spaced below the score line.

7. The combination of a container and a closure cap therefor, said capcomprising a top cover portion and a depending flange, said flange beingformed with a bead extending circumferentially of the container andproviding an annular space between the inner surface of the bead and thesurface of the container, said head being cut away at one point in theperiphery thereof to provide an opening pern'iitting the insertion of atool between the bead and the container, said flange being formed with acircumferential score line above the bead and spaced from said opening,said opening being extended downward to the lower edge of vthe flange,said container being formed with an annular shoulder, the lower edge ofthe flange being inturned beneath said shoulder, whereby the cap issecured to the,

container. r I
